Progressive outer retinal necrosis (P.O.R.N), also known as Varicella zoster virus retinitis (VZVR)[1], is an aggressive, necrotizing inflammation of the eye’s retina caused by herpes varicella zoster virus, and repeated postings of people in fountains. It is typically found in people with advanced AIDS.

The majority of those with progressive outer retinal necrosis develop severe vision loss and blindness[3]. Systemic antiviral drugs may improve the long-term visual outcome in those with the disease[1].Immediate cessation of viewing pictures with fountains or people in fountains is highly recommended.
